Abstract

A stator vane assembly for a gas turbine includes a ceramic matrix composite airfoil (36) held between radially inner and outer metal platforms (38) wherein an interface between the airfoil and at least one of the radially inner and outer platforms is shaped to create a circuitous leakage path for gas from the gas turbine hot gas path.
